Find magnitude and direction of these vectors

Click For Summary

Homework Help Overview

The discussion revolves around finding the magnitude and direction of the vector resulting from the subtraction of two vectors, A and B, both with a magnitude of 3m. Participants explore the implications of vector direction and the conditions under which the subtraction yields different results.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question whether the result of A - B is simply zero, considering the magnitudes are equal, while others emphasize the importance of the angle between the vectors in determining the result.

Discussion Status

There is ongoing exploration of the conditions affecting the outcome of the vector subtraction. Some participants have provided insights into the significance of direction and the geometric interpretation of vectors, but no consensus has been reached.

Contextual Notes

Participants are discussing the implications of vector direction and the need for additional information regarding the angle between the vectors to accurately determine the result of the subtraction.

Homework Statement



Find the magnitude and direction for the vector A-B. Vector A=3m, Vector B=3m

Homework Equations





The Attempt at a Solution



Wouldn't it just be 0?
3-3=0

Thank you very much

It depends on the angle between them.
 
Thank you very much

If the only vectors are A=3.00m and B=3.00, vector -b would be -3.00, right? So wouldn't the distance be 0m? Or is this totally wrong?

Thank you
 
A vector has magnitude and direction, to talk about a vector of just 3m is meaningless.
If they were in the same line then A - B would be zero.
If they were at right angles the distance would be 4.2m
 
Thank you very much
